SEOUL, SOUTH KOREA, May 22, 2017-- Dr. Yiseok Hong has been included in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.With a changing world comes changing markets, and it can be difficult to get a grasp on how economic situations change globally. Dr. Hong has been working since the '90s to develop sophisticated mathematical simulations to handle just these circumstances. He seeks to apply his expertise in econometrics and international economics to make South Korea a more advanced country.Dr. Hong entered the field to understand economic theory and how it influenced Korea. He began at home, earning his bachelor's degree in economics at Seoul National University in 1980. To get an international point of view, he furthered his studies at the University of Rochester, earning a master's degree in economics. He attributes his success to the tutelage of Professors Adrian Pagan, Lionel McKenzie and Ronald Jones at Rochester. It was also during this time that he wrote his Ph.D. thesis on "nonparametric estimation and its applications." Dr. Hong would go on to author several scholarly publications on the technique, which uses complex mathematical models to simulate the effects of economic risk. He is excited to apply his expertise to the use of big data technology like Hadoop and Spark in the fields of finance, dynamic general equilibrium analysis, and macroeconomics.Though application is his ardent passion, Dr. Hong is also an educator, and began his career as a lecturer in the Department of Economics at the Korean University of Foreign Studies. In 1994 he became a research fellow with Daewoo Research Institute. Today, Dr. Hong can be found teaching at Seokyeong University, where he is the chairman of the Department of Economics and Finance. He has held the role since 1997, interrupted only by a brief sojourn as a visiting scholar at the University of Rochester in 2010. He also holds a joint appointment with the Division of Business Administration as an associate professor. Dr. Hong has also served as editor with the Social Science Review at Seokyeong University since 2015.Dr. Hong has served as referee of the Korean Economic Review, the Journal of Economic Theory and Econometrics, and the Seoul Journal of Economics. He was an abstract reviewer for the GTAP Conference from 2013 to 2017. He hopes to continue developing correspondence with other economists on an international level.About Marquis Who's Who :Since 1899, when A. N.

Mobile communication companies in Korea choose different mobile platforms from each other so that developers have to create contents for each of the platforms according to their different characteristics or undergo a converting process to provide the game contents to consumers. In this paper, in order to resolve such problems the game contents of the existing mobile platform, WIPI(Wireless Internet Platform for Interoperability), will be analyzed. Then a platform mapping engine will be implemented in order to convert the game contents for use on a smart platform, Windows Mobile. A mobile contents converter system has enabled contents to be transferred into smart platforms within a short time, so that the time and money it takes to launch services for different mobile communication companies can be reduced. © 2011 Springer-Verlag.

For each platform, for smart phone contents, a unique development environment exists and thus suitable development methods and development languages must be used for each platform. A problem of this development environment is that when contents are created for a number of platforms, an increase in expenses occurs. SVM(Smart Virtual Machine) is a virtual machine solution which is being developed to overcome this problem by using SIL(Smart Intermediate Language) as an intermediate language. SIL is capable of accommodating ISO/IEC C++, Java, Objective-C and other object-oriented programming. In this paper, the Objective-C compiler for the virtual machine is designed and virtualized which creates stack based virtual machine codes, not objective codes when using contents previously developed for the use on other platforms. © 2011 Springer-Verlag.

In this paper, we consider a multiuser detection technique when the signal sparsity is changing over time. The key ingredient of our method is a clever switching between the CS reconstruction algorithm and classical detection depending on the sparsity level of the signals being detected. Since none of these approaches is uniformly better in a situation where the sparsity level is varying, proposed switching algorithm can effectively combine the merits of both. We show that the proposed switching algorithm provides substantial performance gain over individual algorithms in the multiuser detection of CDMA downlink. © 2012 IEEE.

This paper proposes a method for optimizing and parallelizing a pedestrian detection algorithm based on CENTRIST in the embedded environment. Pedestrian detection is applied to various areas, but there is a difficulty in the real-time processing of pedestrian detection in the embedded environment. In this paper, a pedestrian detection algorithm that has improved performance by reducing unnecessary memory access due to duplicate computations for real-time processing. The proposed algorithm was implemented in the ALDEBARAN embedded processor(300MHz) which can perform parallel processing. For efficient parallel processing, images were divided into halves which were then processed separately in two CPU cores and the volume of computations was balanced between the two CPU cores. For input images, 512x360 sized images were used. The single core showed the performance of 3.1 frames per second. In the dual core for which the wait time in the process of parallelizing was reduced, the performance improved by about 55% to 4.8 frames per second. © 2014 SERSC.

A bioassay-guided fractionation of an ethanol extract of Buthus martensi Karsch led to the isolation of a potent α-glucosidase inhibitor (compound S). The structure was elucidated as a novel β-carboline glucoalkaloid, harmanyl β-d-glucopyranoside, on the basis of spectral data, including 1H NMR, 13C NMR, 1H-1H COSY, NOESY, and HMBC. Compound S showed potent inhibitory activity against α-glucosidase, with an IC50 value of 24 μM. A Lineweaver-Burk plot indicated that its inhibition of α-glucosidase was uncompetitive, with a Ki value of 16.1 μM. © 2012 Elsevier Ltd. All rights reserved.

An attempt is given to the employment of spatial prediction (SP) models such as kriging and splines into the estimation of response surface in central composite design (CCD), with a view to enhancing the reproducibility of actual response surfaces by combining CCD and SP. A brief introduction to CCD and SP is presented in the paper, and a numerical example is examined to discuss on the merits of the method. In the modeling process, a computer program is developed to carry out the spatial prediction. Software for plotting is utilized in order to represent the response surfaces graphically. © 2016 IEEE.

In this paper, we have considered for study the central composite design (CCD) with a view to extending the related second-order response surface models. In the CCD, there are three types of design points, such as the factorial, axial and center points. We devised a new type of CCD for the experiments with replicate runs at such design points, not just at the design center. This type of experimental design, named as CCD-R, proves to be flexible in the sense that there exist a myriad of exactly orthogonal and nearly rotatable designs. It is also demonstrated that the proposed CCD-R is useful, especially when a number of replicate runs are desired in the experiment for one reason or another. Since the second-order generalized regression models provide a good framework of the method, an attempt is given to the problem of logistic regression analysis for categorical data based on the CCD-R. © Springer-Verlag Berlin Heidelberg 2015.

Recently, 3D printers have attracted increasing attention due to their popularization and high performance, resulting in expanded application ranges. Popularization implies that people are using 3D equipment when they do not have underlying knowledge about it. High performance can be obtained from several aspects of 3D printing processes such as an efficient way to generate a 3D model from images or drawings. In this paper, two topics are considered: improvement of the precision of 3D models from two-dimensional (2D) images, and their conversion into G-code in a time-efficient way. When making 3D data models using 2D images, there are several issues to consider. In this study, some case studies using standard software are used to obtain data in which adjustments are made. The conversion time strongly depends on the subject size. Although the amount of code and its complexity are high, 3D printers should be able to handle this process in a practical time. A system model is proposed to shorten the essential data conversion time for a high-performance process. A distributed processing algorithm for converting standard template library (STL) files to G-code is proposed as a means to process 3D model data. © 2014, The Minerals, Metals & Materials Society.

A heteropolysaccharide possessing strong inhibitory activity against cholesterol esterase, namely PS-A, was isolated from water extracts of Cordyceps sinensis by activity-guided fractionation. The molecular weight of PS-A was estimated as 4.6×105 Da. Compositional analysis revealed the presence of D-glucose, D-galactose, and D-mannose at a molar ratio of 2:1:1. The 1H and 13C nuclear magnetic resonance spectra, correlation spectroscopy, nuclear Overhauser effect spectroscopy, and heteronuclear multiple bond correlations experiment established the structure of PS-A as follows: →3)α-D-glcp(1→3)β-D-glcp(1→3)β-D-glcp(1→ 2 ↑ 1 α-D-manp Results of the in vitro enzyme assay showed strong inhibition of cholesterol esterase by PS-A, with an IC50 value of 12.7 μg/mL, suggesting the possibility of its usefulness as a potential agent for control of hypercholesterolemia.
